Apache RewriteEngine simple reminder (Apache 2.4+)

.htaccess

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteBase /
    # OR has a HIGHER precedence than the implicit AND of subsequent RewriteCond directives.
    RewriteCond %{REQUEST_URI} !/app/assets/.*
    # Disallow everything below /app/
    RewriteCond %{REQUEST_URI} /app/.* [OR]
    # Disallow dotfiles
    RewriteCond %{REQUEST_URI} /\..*
    RewriteRule ^.* - [F,L]
    
    # Redirect a direct requests to folders to index.php 
    RewriteCond %{REQUEST_URI} /.*/
    RewriteCond %{REQUEST_URI} !/.*/[^/]+$
    RewriteRule ^(.*)$ ?dir=$1 [L,R=307]    	
</IfModule>

• RewriteRule with included condition, no RewriteCond
• RewriteRule with multiple RewriteCond directives
• RewriteRule with regex backreference
